Research methodology refers to research methods, and the main research methods include investigation, observation, literature research, qualitative analysis and quantitative analysis.

1, survey method

Investigation is one of the most commonly used methods in scientific research. It is a purposeful, planned and systematic method to collect materials about the actual situation or historical situation of the research object. The investigation method comprehensively uses historical methods, observation methods, conversations, questionnaires, case studies, tests and other scientific methods to have a planned, in-depth and systematic understanding of educational phenomena, and to analyze, synthesize, compare and summarize a large number of data collected in the investigation, thus providing people with regular knowledge.

Questionnaire survey is the most commonly used survey method.

2. Observation method

Observation method refers to a method in which researchers use their own senses and auxiliary tools to directly observe the research object according to a certain research purpose, research outline or observation table, so as to obtain information. Scientific observation is purposeful, planned, systematic and repeatable.

3. Literature research method (literature retrieval method)

Literature research method is a method to obtain information by investigating literature according to certain research purposes or topics, so as to comprehensively and correctly understand and master the problems to be studied. Literature research methods are widely used in various disciplines.

Its functions are as follows: ① It can understand the history and present situation of related problems and help to determine the research topic. ② It can form an overall impression of the research object, which is helpful for observation and visit. ③ Contrast data of real data can be obtained. (4) help to understand the whole picture of things.

4. Quantitative analysis method

In scientific research, quantitative analysis can make people know the research object more accurately, so as to reveal the law more scientifically, grasp the essence, clarify the relationship and predict the development trend of things.

5. Qualitative analysis method

Qualitative analysis is the qualitative analysis of the research object. Specifically, the method of induction and deduction, analysis, synthesis and abstract generalization is used to process the obtained materials, so as to get rid of the rough, get rid of the false and keep the true, understand the essence of things and reveal their internal laws.
